    Yakuza JDM Race Spec 2H in an HJ60

    Does anyone know the slope accurately? You can calculate power from slope, speed and vehicle weight.

    Any detailed checklist for SAFELY turboing a 2H engine?

    IMO the only way to safely turbo an old IDI engine is to run low boost and no extra fuel. You will gain cleaner burn, a few percent efficiency/economy gain and cooler running engine. Any increase in fuel will increase engine loads and shorten engine life. Engines of this age tend to already...

    Turbo advice for 3L camper cabover rig

    A bigger turbine means less boost, hotter EGT, more smoke and worse response. That TD04 was used on 100kW diesels and you'll be nowhere near that. On a diesel boost is cooling. The CT20 turbine is an old design that is really inefficient and would be an exhaust brake if it was smaller. The...

    Turbo advice for 3L camper cabover rig

    I don't think you'll find a genuine unit. I would buy from a reputable seller and you'll get a quality balanced unit. Kinugawa, mambatek etc. I think it's a unique flange. Part number I have is 49177-06430 There will be other similar size turbos with different flanges. But that's it's own...

    Turbo advice for 3L camper cabover rig

    CT20 is old, inefficient and hard to get parts for. Get a MHI TD04-4 which was used on 2.5 litre Mitsubishi and BMW diesels. Safe boost is single digits (i.e 9psi). Tune it so it doesn't smoke and you'll be fine.

    You'll have to check different markets. Here in NZ we have DPF but not ad-blue. I presume Australia is the same. It will be difficult to find a market that doesn't have DPF these days. Maybe Africa.

    Compound Turbos on a 2nd Edition B Engine

    Advance angle is the change in timing. It's absolute timing you want to compare. Isuzu engines are spill timed. That's where you rotate the crank until the injection pump starts to deliver fuel. 4BD1 (direct injection no turbo) is 10 deg BTDC 4BD1T (direct injection turbo) is 13-14 deg 4BD2T...

    Also. Direct injection engines run a whole lot more timing advance than indirect injection engines do.

    1HD-FT Synthetic Engine Oil Info

    Back then Toyota stretched the FTE intervals out to an enormous 7,500km. Because the FTE ran a whole lot cleaner than the earlier engines. Less soot in the oil. Note the progression in oil standards. CF oil on that chart is C for "compression ignition" (diesel) and F was the grade. Now...

    Bigger turbo and injectors will only help when you've got a bigger injection pump. Stock doesn't have much head-room: OM617 Performance Review - https://www.4btswaps.com/threads/om617-performance-review.74457/

    Interesting, thanks. How is your Hilux for fuel economy? Do you have ad-blue? Here we have only the 2.8 1GD without ad-blue. Fuel consumption isn't great.

    1HD-FT Synthetic Engine Oil Info

    All engine oils these days are dual rated. They have a spark ignition (petrol/gas) rating and a compression ignition (diesel) rating. They are all majorly better than they were 30-40 years ago. Diesel engine oils used to be better at handling soot, but it's not really an issue now. Diesels...

    1HD-FT Synthetic Engine Oil Info

    The solution to your oil queries is right there ^^. Use that for your 1HD-FT and your life gets way simpler. The only reason not to is cost. I use a Motorex 5W30 that's VW approved for all my newer engines and a cheaper 10W40 for my 4BD1T. All these oils are far better than the ones available...

    I'd use 10W40 and minimise your oil stores.

    That'll be pretty sluggish in your winters. If you plug-in or garage you should be okay.

    Convert my FZJ80 to OM603 ?

    I've put the performance review link in the post above. 300Nm and 110kw is the limit for the stock injection pump. 220 ft-lb and 150hp.

    Convert my FZJ80 to OM603 ?

    What's your end goal and reason for swapping to diesel? This is starting to look like an incredibly expensive way to get very little difference in fuel economy or range. A maxed out OM617 with better turbo still doesn't have the power or torque your 1FZ has. You need thousands in injection...

    Convert my FZJ80 to OM603 ?

    Makes perfect sense to upgrade an existing one in a G-wagen. But not so much to shoe-horn one into a bigger and heavier Toyota first. Indirect injection diesels are on average 20% less efficient than direct injection. The most efficient petrol engines have similar fuel economy to the worst...

    Convert my FZJ80 to OM603 ?

    I don't think the torque, power or efficiency of an OM617 will work in an 80.
